Check the axial run-out on the flywheel surface (B).

The axial run-out must not be greater than 0.03 mm

as a total reading on the dial indicator for every 25

mm radius of the flywheel (calculated from the cent-

During this measurement, the crankshaft must be

pressed forward to prevent the axial run-out of the

crankshaft from affecting the reading.

stages to 9 Nm. Do not start the engine until the

locking fluid has hardened.

Install the drive components at the rear of the en-

gine.

The collar is installed on the flywheel by heating it.

When a new collar is installed, ensure that it is not

heated above 250°C. Check that the chamfering on

the teeth is facing in the correct direction.
